Fundamental Issues of New-type Power System Construction
The construction of the new-type power system represents a primary imperative for the attainment of"dual carbon"target,which is currently in the critical stage of accelerating progress.It is urgent to clarify the fundamental issues of the construction of the new-type power system,so as to provide reference and guidance.This paper describes the major changes of power supply,power grid,load and energy storage form of new-type power system;on this basis,the scientific and economic problems of new-type power system construction are proposed from the aspects of power balance theory,stability mechanism,cost estimation,optimization and sharing,and finally,the key technical directions supporting the construction of new-type power system are proposed.
